How can I go step by step in Xcode while debugging with a keyboard shortcut? I'd like to make step over and step into with the keyboard, I've looked for keysheets and such but didn't find keys for that particular actions.
This is an easy one indeed. Go to Xcode
>Preferences
>Key Bindings
and search for 'step
'. There you can define your shortcuts for each action.
PS: As @Jenn noted below "Pause/Continue" is missing from this list, which is by default bound to ⌃⌘Y (ctrl + command + Y)
